Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans

Description: The purpose of this study was to determine relationships between acculturation level, generational status, and gender with acculturative stress. Acculturation level was determined by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) and acculturative stress was determined by the Societal, Attitudinal, Familial and Environmental Acculturative Stress Scale-Children's Version (SAFE-C). Subjects included 1268 Hispanic children ages 11-15. In order to validate the usefulness of the ARSMA-II with this sample, analyses were conducted between acculturation level and generational status. The Pearson product moment correlation (r=.44) and the ANOVA between the mean acculturation score and generational status were significant. However, the mean acculturation score from this study was considerably lower than the ARSMA-II score; therefore, new acculturation levels were developed to establish local adolescent norms for the ARSMA-II. All analyses involving acculturation levels were conducted using both the ARSMA-II and new acculturation levels because 300 subjects were reclassified with the new norms. Significant results were similar using both acculturation levels; however, there were more between group differences using the new acculturation levels. It was hypothesized that as acculturation level increased toward the Anglo culture, acculturative stress would decrease. The one-way ANOVA confirmed this relationship. It was also hypothesized that as generational status increased, acculturative stress would decrease. A one-way ANOVA also supported this hypothesis. In order to replicate previous findings on gender, a one-way ANOVA was conducted with acculturative stress and acculturation level. Results for both were non-significant. Overall findings indicate that generational status and acculturation level have a significant impact on acculturative stress in Hispanic children; however, gender does not seem to be a factor. Findings emphasize the importance of addressing cultural issues in the assessment, intervention, and treatment of acculturating Hispanic children. Furthermore, the ARSMA-II appears to be a useful instrument in assessing acculturation level in young adolescent Hispanics though new ...

N-Acylethanolamine Metabolism During Seed Germination: Molecular Identification of a Functional N-Acylethanolamine Amidohydrolase

Description: N-Acylethanolamines (NAEs) are endogenous lipid metabolites that occur in a variety of dry seeds, and their levels decline rapidly during the first few hours of imbibition (Chapman et al., 1999, Plant Physiol., 120:1157-1164). Biochemical studies supported the existence of an NAE amidohydrolase activity in seeds and seedlings, and efforts were directed toward identification of DNA sequences encoding this enzyme. Mammalian tissues metabolize NAEs via an amidase enzyme designated fatty acid amide hydrolase (FAAH). Based on the characteristic amidase signature sequence in mammalian FAAH, a candidate Arabidopsis cDNA was identified and isolated by reverse transcriptase-PCR. The Arabidopsis cDNA was expressed in E. coli and the recombinant protein indeed hydrolyzed a range of NAEs to free fatty acids and ethanolamine. Kinetic parameters for the recombinant protein were consistent with those properties of the rat FAAH, supporting identification of this Arabidopsis cDNA as a FAAH homologue. Two T-DNA insertional mutant lines with disruptions in the Arabidopsis NAE amidohydrolase gene (At5g64440) were identified. The homozygous mutant seedlings were more sensitive than the wild type to exogenously applied NAE 12:0. Transgenic seedlings overexpressing the NAE amidohydrolase enzyme showed noticeably greater tolerance to NAE 12:0 than wild type seedlings. These results together provide evidence in vitro and in vivo for the molecular identification of Arabidopsis NAE amidohydrolase. Moreover, the plants with altered NAE amidohydrolase expression may provide new tools for improved understanding of the role of NAEs in germination and seedling growth.

Adapting Filial Therapy for Families who have a Child with a Life-Threatening Illness

Description: Utilizing a collective case study design, I examined and described the filial therapy (FT) process and adaptations discovered to be necessary and unnecessary in working with families who have a child with a life-threatening illness in the hospital setting. Data from a total of 7 parents was utilized, including those who terminated early, in order to gain a greater understanding of adapting FT for families who have a child with a life-threatening illness and their participation patterns. The parents attended 10 one- to two-hour FT sessions. The data was analyzed to examine for themes, patterns and relationships intrinsically with each case participant, as well as across cases. Analysis indicated that parents with a child with a life-threatening illness had great difficulty committing to attend FT; and a high rate of attrition occurred for those who did commit. A theme regarding flexibility was found to be of eminent importance in a variety of manifestations including therapeutic methods, session format, location and time of sessions, and intense vs traditional FT. Therapeutic adaptations in flexibility found to be important including openness to cathartic and personal parenting sessions, tolerance of forgetfulness, and lowering typical therapeutic concerns of dependency in the relationship. An inability for parents in this situation to benefit from intense FT methods was also noted. Changes noted in the child of focus included increased confidence, increased cooperation in the medical setting, increased communication with the parent and with medical staff regarding medical issues, and increased communication with the parent regarding personal feelings and issues. Changes noted in the parents included increased confidence in parenting skills, increased awareness of the child's perceptions of the environment, increased tolerance in allowing the child to struggle in and out of the medical setting, with both emotional and physical pain in order to gain coping skills, increased ...

Adaptive Planning and Prediction in Agent-Supported Distributed Collaboration.

Description: Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made in this area, it remains a fertile area for further development. One application of agents under careful scrutiny is the automated negotiation of conflicts between different user's needs and desires. Many techniques require explicit user models in order to function. This dissertation explores a technique for dynamically constructing user models and the impact of using them to anticipate the need for negotiation. Negotiation is reduced by including an advising aspect to the agent that can use this anticipation of conflict to adjust user behavior.

Adherence/Diffusion Barrier Layers for Copper Metallization: Amorphous Carbon:Silicon Polymerized Films

Description: Semiconductor circuitry feature miniaturization continues in response to Moore 's Law pushing the limits of aluminum and forcing the transition to Cu due to its lower resistivity and electromigration. Copper diffuses into silicon dioxide under thermal and electrical stresses, requiring the use of barriers to inhibit diffusion, adding to the insulator thickness and delay time, or replacement of SiO2 with new insulator materials that can inhibit diffusion while enabling Cu wetting. This study proposes modified amorphous silicon carbon hydrogen (a-Si:C:H) films as possible diffusion barriers and replacements for SiO2 between metal levels, interlevel dielectric (ILD), or between metal lines (IMD), based upon the diffusion inhibition of previous a-Si:C:H species expected lower dielectric constants, acceptable thermal conductivity. Vinyltrimethylsilane (VTMS) precursor was condensed on a titanium substrate at 90 K and bombarded with electron beams to induce crosslinking and form polymerized a-Si:C:H films. Modifications of the films with hydroxyl and nitrogen was accomplished by dosing the condensed VTMS with water or ammonia before electron bombardment producing a-Si:C:H/OH and a-Si:C:H/N and a-Si:C:H/OH/N polymerized films in expectation of developing films that would inhibit copper diffusion and promote Cu adherence, wetting, on the film surface. X-ray Photoelectron Spectroscopy was used to characterize Cu metallization of these a-Si:C:H films. XPS revealed substantial Cu wetting of a-Si:C:H/OH and a-Si:C:H/OH/N films and some wetting of a-Si:C:H/N films, and similar Cu diffusion inhibition to 800 K by all of the a-:S:C:H films. These findings suggest the possible use of a-Si:C:H films as ILD and IMD materials, with the possibility of further tailoring a-Si:C:H films to meet future device requirements.

Age and Responses to the Events of September 11, 2001

Description: Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience of older adults, it seems that coping style is highly important, while hardiness and the impact of history-graded events does not explain the resilience of older adults.

An Analysis of Advisory Committee Activities in a Successful Public School Bond Election

Description: The purpose of this study was to determine the perceived effectiveness of specific advisory committee activities during a school bond proposal and election process. The study began with an extensive review of the literature on the use of advisory committee activities in school districts for the purpose of promoting a school bond issue. This revealed that school officials maintaining a low profile, the presence of a diverse community task force, focusing on YES voters, involving the committee in early planning, focusing on disseminating information, and focusing on benefits to children and the community are all important in the passage of a school bond election. A survey was developed and administered to committee members, school board members and school district administrators in a North Texas school district that had successfully completed a bond election. Survey respondents consistently supported the practices put into place by the studied school district, which closely mirrored the activities espoused in the research. Respondents believed the diversity of the task force and the roles of the committee members to be crucial to the passage of the bond. The only subcategory of questions that drew mixed reviews and positions of support was that of the need for the administration and board to maintain a low profile. Participants in the survey viewed having a diverse community task force, focusing on YES votes, involvement in early planning, focusing on disseminating information, and focusing on benefits to children and the community as being important to the successful passage of the school bond election, with clear dissemination of information being the most important activity of the committee.

Analysis of Leadership Perceptions Using Multirater Feedback.

Description: Performance improvement intervention begins with assessment. How that assessment is interpreted can mean the difference between success and failure. Previous research of 360-degree feedback instruments has tried to reconcile the differences between multiple rater groups. Rather than searching for agreement, this research proposes to understand the meaning of the differences using multirater feedback. Individuals determine ratings based upon their own perspective and building upon the understanding of rater perspective may result in improved assessments. Data from an existing data set was processed using a second-order CFA in structural equation modeling. Covariance between the second-order factors and rater groups determined the difference in how each rater group perceived the leader.

Analysis of Perceptional Differences Among Department Chairs, Faculty, and Instructors Toward the Barrier to Using Multiple Teaching Strategies in Two-Year Technical and Community College Electronics Courses

Description: The purpose of this study was to identify and analyze perceptional differences among department chairs, faculty, and instructors toward the barrier to using multiple teaching strategies in two-year technical and community college electronics courses. The literature review focused on defining multiple teaching strategies and identifying and discussing four major perceived barriers to implementing them in the electronics classroom: student, resources, classroom environmental, and teacher training/teaching technology. The targeted population consisted of 150 out of 231 electronics teaching technical and community college department chairs, faculty, and instructors throughout the state of Texas. In actuality, the targeted population's breakdown consisted of 36 full-time electronics teaching department chairs, 96 full-time electronics teaching faculty and instructors, and 18 part-time electronics teaching faculty and instructors who were actively involved in the delivery of instruction in their respective schools. Analysis of the data revealed that: (1) there are no significant differences among the perceptions of department chair people, faculty, and instructors toward the four perceived barriers to implementing multiple teaching strategies in a post-secondary electronics program; and (2) there are no significant differences in the perceptions electronics faculty members categorized by years teaching experience toward each of the four perceived barrier categories to implementing multiple teaching strategies in a post-secondary electronics program. However, further research is needed to substantiate what other barriers exist that may have an impact upon utilizing multiple teaching strategies in two-year technical and community college electronics courses.

An Analysis of the Effect of Distance Learning on Student Self-Efficacy of Junior High School Spanish Students.

Description: Prior to the development of interactive television, schools that were either geographically isolated or financially restricted were often unable to provide courses that may have been essential for students. Interactive television has helped such school districts provide appropriate courses for their students. Because student self-efficacy is a significant indicator of student success, the relationship between distance learning and students' self-efficacy requires research. The problem of the study was to examine the impact of site location in a distance learning environment on student self-efficacy in Spanish instruction. The participants in this study were junior high school students enrolled in distance-learning Spanish classes at two junior high schools in a north central Texas independent school district. All of the students were taught by the same instructor. The age range of the students was from 11 to 14 years of age, and all students were in either the seventh or the eighth grade. Students took a modified version of the Motivated Strategies for Learning Questionnaire at the end of each treatment. Using the counterbalanced design, each subject was matched to themselves. T-tests for nonindependent samples were used to compare the two treatments. The findings indicate that there is no significant difference in the level of student self-efficacy by site location. The findings in this study support the use of distance learning as a medium for Spanish instruction at the junior high school level. Because of the strong statistical relationship between self-efficacy and student performance, teachers and administrators can reasonably believe that site location will not hamper their students' success.

An Analysis of the Genesis of Motive, Rhythm, and Pitch in the First Movement of the Sonata for Two Pianos and Percussion by Béla Bartók.

Description: This dissertation presents evidence that Béla Bartók created his masterwork, the Sonata for Two Pianos and Percussion (1937), in a very complex period of his life. Since it was a mature piece, Bartók utilized typically "Bartókian" compositional techniques and styles. His ethnomusicological studies were also influential factors in the creation of the Sonata for Two Pianos and Percussion. We can be witness to how different the first draft was to the published version; the minor and major changes are revealed in the draft study of the Sonata for Two Pianos and Percussion 's first movement. These changes allow today's musicians to reconstruct the compositional process. The first movement introduces some interesting uses of sonata form, to be explored in more detail in the analysis. Starting with linear analysis, the basic motives and rhythmic patterns are discussed and supported with Bartók's own explanations. The conclusion of this study has important ramifications for performance: it eases up the pressure on the performers, since problematic passages are analyzed and explained - preparing the players' mentally for the performance. This is music which is hard to play and difficult to analyze. The analysis, combining the results of both theoretical and musicological studies, is intended to help both analysts and performers understand the genesis of the piece and, for performers, to execute the music in the best possible manner.

The Anatomy of Academic Dishonesty: Cognitive Development, Self-Concept, Neutralization Techniques, and Attitudes Toward Cheating

Description: This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive development and self-concept in academic dishonesty represent major findings.

Appellate Recruitment Patterns in the Higher British Judiciary: 1850 - 1990

Description: This study seeks to advance the understanding of appellate promotion in the senior judiciary of Great Britain . It describes the population and attributes of judges who served in the British High Courts, Court of Appeal, and Appellate Committee of the House of Lords (i.e., Law Lords) from 1850 to 1990. It specifically builds upon the work of C. Neal Tate and tests his model of appellate recruitment on a larger and augmented database. The study determines that family status, previously asserted as having a large effect on recruitment to the appellate courts, is not as important as previously believed. It concludes that merit effects, professional norms, and institutional constraints offer equally satisfactory or better explanations of appellate recruitment patterns.

An Assessment of Technology Learning Styles, Skills, and Perceptions Among Teachers of Grades Pre-Kindergarten Through Four.

Description: This study investigated whether a relationship exists between learning style and the self-reported technology-related needs, beliefs, stages of adoption, software expertise, and technology competencies of teachers in a large suburban school district. The Gregorc Style Delineator was used to identify dominant learning style, and the Snapshot Survey was used to measure technology-related needs, beliefs, stages of adoption, and software expertise. Technology competencies were measured using the Technology in Education Competency Survey. Data collected from 499 participants was included in data analysis. The study was conducted at each of the 12 elementary schools of a large suburban district in the Dallas-Fort Worth Metroplex. The findings suggest that there is a significant relationship between learning style and the technology-related needs, stages of adoption, software expertise, and competencies of teachers. The relationship between learning style and technology-related needs was significant at the p < .01 level. The relationships between learning style and technology-related stages of adoption, software expertise, and technology competencies were significant at the p < .05 level. Members of the abstract sequential [AS] learning style group reported having significantly fewer needs and significantly higher stages of adoption, software expertise, and competency than members of one or more of the other learning style groups. More research is recommended to determine whether these findings could be utilized to improve teacher staff development in the area of technology. Possible applications may include mentoring programs and the customization of training models to more closely match learning style profiles.

An Assessment of the Effectiveness of the CHAMPS/Life Skills Program at the University of North Texas: A Pilot Study

Description: This study seeks to determine the effectiveness of the Challenging Athletes Minds for Personal Success (CHAMPS)/Life Skills program at the University of North Texas, as perceived by the student athletes who participate or participated in this program. The study attempts to measure the extent to which the student athletes feel that the program had value; if they received helpful information to support them through their college career to career transition; if the student athletes felt that the program provided them with skills to encourage better self-esteem; and if they believed that the CHAMPS/Life Skills program provided them with leadership and character education. The study, conducted in the Fall of 2003, had 163 respondents. An instrument was developed to determine student athletes' perceptions of the effectiveness of the CHAMPS/Life Skills program at UNT. The instrument consisted of 30 questions using a Likert-type scale. A Mann-Whitney U, a non-parametric t-Test, was utilized to analyze the data. This type of t-Test was used because it is specifically designed to compare the means of the same variable with two different groups and account for non-homogeneous groups. The lack of homogeneity was very likely influenced by the unequal group sizes. Generally, all aspects of the CHAMPS/Life Skills program at UNT were found to be positive by each subgroup. Student athletes found value in the CHAMPS/Life Skills program at UNT. In three of the four components studied, males had a statistically stronger feeling than females. Minority status had no statistically significant impact on the results in any of the four components studied. For the variable measuring the number of years in the program, a significant difference existed in three of the four components studied. The study shows that if a student athlete was involved in the program for more than two years, the CHAMPS/Life Skills program ...

Camille Saint-Säens' Piano Concerto No. 5 in F Major, Opus 103: An Analytical Study of Form, Compositional Techniques, and a Performance Perspective

Description: The majority of books about Saint-Säens cover his life, compositions, contemporaries, and French music in general. Although his life is well documented, most sources present only brief analyses of his works; there is not one single comprehensive and exhaustive study of the Piano Concerto in F Major, Opus 103, available in the current literature. This study aims at filling the gap by providing other musicians interested in performing this piece with an initial study-guide. The research for this study focuses on several aspects of Saint-Säens' music. The currently available literature and past research is thoroughly examined, appraised, and quoted when relevant to the discussion. The original score of the concerto is analyzed regarding its form, compositional style, and performance indications. Diagrams, charts, and musical examples are presented to illustrate and substantiate the researcher's conclusions. Chapter I presents the topic and purpose of this study, a brief biography of Saint-Säens, a chronological overview of his five piano concertos, and the historical background of the Piano Concerto No. 5 in F Major, Opus 103. Chapter II presents a formal analysis and a compositional analysis of Opus 103. Chapter III presents a perspective of Saint-Säens playing style and performance recommendations by the author. Chapter IV concludes this study by determining the importance of Opus 103 in piano literature and by explaining the reason that performers with professional aspirations should consider including this concerto in their repertoire.

Cognitive Playfulness, Innovativeness, and Belief of Essentialness: Characteristics of Educators who have the Ability to Make Enduring Changes in the Integration of Technology into the Classroom Environment.

Description: Research on the adoption of innovation is largely limited to factors affecting immediate change with few studies focusing on enduring or lasting change. The purpose of the study was to examine the personality characteristics of cognitive playfulness, innovativeness, and essentialness beliefs in educators who were able to make an enduring change in pedagogy based on the use of technology in the curriculum within their assigned classroom settings. The study utilized teachers from 33 school districts and one private school in Texas who were first-year participants in the Intel® Teach to the Future program. The research design focused on how cognitive playfulness, innovativeness, and essentialness beliefs relate to a sustained high level of information technology use in the classroom. The research questions were: 1) Are individuals who are highly playful more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less playful? 2) Are individuals who are highly innovative more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who are less innovative? 3) Are individuals who believe information technology use is critical and indispensable to their teaching more likely to continue to demonstrate an ability to integrate technology use in the classroom at a high level than those who believe it is supplemental and not essential? The findings of the current study indicated that playfulness, innovativeness, and essentialness scores as defined by the scales used were significantly correlated to an individual's sustained ability to use technology at a high level. Playfulness was related to the educator's level of innovativeness, as well. Also, educators who believed the use of technology was critical and indispensable to their instruction were more likely to be able to demonstrate a sustained ...

A comparison of traditional and IRT factor analysis.

Description: This study investigated the item parameter recovery of two methods of factor analysis. The methods researched were a traditional factor analysis of tetrachoric correlation coefficients and an IRT approach to factor analysis which utilizes marginal maximum likelihood estimation using an EM algorithm (MMLE-EM). Dichotomous item response data was generated under the 2-parameter normal ogive model (2PNOM) using PARDSIM software. Examinee abilities were sampled from both the standard normal and uniform distributions. True item discrimination, a, was normal with a mean of .75 and a standard deviation of .10. True b, item difficulty, was specified as uniform [-2, 2]. The two distributions of abilities were completely crossed with three test lengths (n= 30, 60, and 100) and three sample sizes (N = 50, 500, and 1000). Each of the 18 conditions was replicated 5 times, resulting in 90 datasets. PRELIS software was used to conduct a traditional factor analysis on the tetrachoric correlations. The IRT approach to factor analysis was conducted using BILOG 3 software. Parameter recovery was evaluated in terms of root mean square error, average signed bias, and Pearson correlations between estimated and true item parameters. ANOVAs were conducted to identify systematic differences in error indices. Based on many of the indices, it appears the IRT approach to factor analysis recovers item parameters better than the traditional approach studied. Future research should compare other methods of factor analysis to MMLE-EM under various non-normal distributions of abilities.

A Comparison of Trainee and Supervisor Perceptions of Transfer Climate in a Union-Based Training Program.

Description: A supportive work climate is critical for successful transfer of learning. Influences in the work environment affect the trainee's ability to apply new skills to the job. The supervisor can be a significant figure in the trainee's perception of a supportive transfer climate. Little is known of the effect of supervisor participation in the training on transfer climate. The purpose of this study was to identify differences in trainee and supervisor self-perceptions of the factors affecting transfer climate. Additionally, this study examined the effects of supervisor participation in the training program on perceptions of transfer climate. The participants in this study were trainees in a union-sponsored instructor training program and their supervisors. The study found perception gaps between the overall perception of transfer climate and supervisor support. The level of supervisor participation in the training program was not to be a factor in the differences between the trainee and supervisor perceptions. No statistically significant difference exists in the perception of other transfer climate factors: supervisor sanctions, peer support, resistance/openness to change, and feedback/performance coaching. In addition, the study found that supervisor participation in the training made little difference in the perceptions of transfer climate by supervisors and trainees. Studies comparing trainee and supervisor perceptions of transfer climate and the effect of supervisor participation in the training on these perceptions are needed from other organizations before extensive generalizations can be made.

The Concept of Collision Strength and Its Applications

Description: Collision strength, the measure of strength for a binary collision, hasn't been defined clearly. In practice, many physical arguments have been employed for the purpose and taken for granted. A scattering angle has been widely and intensively used as a measure of collision strength in plasma physics for years. The result of this is complication and unnecessary approximation in deriving some of the basic kinetic equations and in calculating some of the basic physical terms. The Boltzmann equation has a five-fold integral collision term that is complicated. Chandrasekhar and Spitzer's approaches to the linear Fokker-Planck coefficients have several approximations. An effective variable-change technique has been developed in this dissertation as an alternative to scattering angle as the measure of collision strength. By introducing the square of the reduced impulse or its equivalencies as a collision strength variable, many plasma calculations have been simplified. The five-fold linear Boltzmann collision integral and linearized Boltzmann collision integral are simplified to three-fold integrals. The arbitrary order linear Fokker-Planck coefficients are calculated and expressed in a uniform expression. The new theory provides a simple and exact method for describing the equilibrium plasma collision rate, and a precise calculation of the equilibrium relaxation time. It generalizes bimolecular collision reaction rate theory to a reaction rate theory for plasmas. A simple formula of high precision with wide temperature range has been developed for electron impact ionization rates for carbon atoms and ions. The universality of the concept of collision strength is emphasized. This dissertation will show how Arrhenius' chemical reaction rate theory and Thomson's ionization theory can be unified as one single theory under the concept of collision strength, and how many important physical terms in different disciplines, such as activation energy in chemical reaction theory, ionization energy in Thomson's ionization theory, and the Coulomb logarithm in ...

Contextualized Risk Assessment in Clinical Practice: Utility of Actuarial, Clinical, and Structured Clinical Approaches to Predictions of Violence.

Description: Assessing offenders' risk of future violent behavior continues to be an important yet controversial role of forensic psychologists. A key debate is the relative effectiveness of assessment methods. Specifically, actuarial methods (see Quinsey et al., 1998 for a review) have been compared and contrasted to clinical and structured clinical methods (see e.g. Hart, 1998; Webster et al., 1997). Proponents of each approach argue for its superiority, yet validity studies have made few formal comparisons. In advancing the available research, the present study examines systematically the type of forensic case (i.e., sexual violence versus nonsexual violence) and type of assessment method (i.e., actuarial, structured clinical, and unstructured clinical). As observed by Borum, Otto, and Golding (1993), forensic decision making can also be influenced by the presence of certain extraneous clinical data. To address these issues, psychologists and doctoral students attending the American Psychology Law Society conference were asked to make several ratings regarding the likelihood of future sexual and nonsexual violence based on data derived from actual defendants with known outcomes. Using a mixed factorial design, each of these assessment methods were investigated for its influence on decision-makers regarding likelihood of future violence and sexually violent predator commitments. Finally, the potentially biasing effects of victim impact statements on resultant decisions were also explored.
